Best soil mixes for seed starting

Share your favorite seed starting mixes. Do you add perlite, compost, or coconut coir?

For seed starting, I really like a mix of peat moss, perlite, and vermiculite in equal parts. This combination provides excellent drainage while retaining moisture, which is crucial for seed germination. If you want to add some organic matter, a small amount of compost can be beneficial, but be careful not to make it too heavy. Coconut coir is also a great option to replace peat moss if you’re looking for a more sustainable choice. Just remember to keep the mix light and airy to help those little seeds thrive!

I find that a mix of coconut coir, perlite, and a bit of fine compost works wonders for seed starting. The coir provides good moisture retention while still allowing for airflow, and the perlite enhances drainage. I usually go for a ratio of 70% coir, 20% perlite, and 10% compost to keep it light and prevent any potential damping off issues. This combination has really helped my seeds germinate quickly and robustly!

I enjoy using a mix of seed starting soil that combines peat moss, perlite, and a touch of worm castings. The peat moss offers a nice balance of moisture retention and aeration, while the perlite ensures good drainage. Worm castings add beneficial nutrients without making the mix too heavy. A ratio of about 60% peat moss, 30% perlite, and 10% worm castings works well for me. This blend has really boosted my germination rates and keeps the seedlings healthy!

Another great option for seed starting is using a blend of organic potting soil, coconut coir, and perlite in a 50-30-20 ratio. The organic potting soil provides a gentle nutrient base, while the coconut coir helps with water retention and air flow, and the perlite ensures excellent drainage. This combination supports strong seedling growth and minimizes the risk of overwatering. Just make sure to moisten the mix before planting your seeds to kickstart the germination process. Happy gardening!
